Levetiracetam (LTA), a piracetam analogue, is an antiepileptic drug (AED) structurally unrelated to other AEDs. The exact mechanism by which LTA acts has not been determined at this time; however, binding sites for the drug have been identified in synaptic plasma membranes of CNS neurons. Secondary alteration in GABA-related enzymes may result from binding to neurons in specific regions of the CNS. While approximately one-fourth of LTA is converted by enzymatic hydrolysis to a carboxylic acid metabolite, the drug has no effect on UDP glucuronyltransferase, epoxide hydrolase, or enzymes in the CYP system, Red-top tube, lavender-top (EDTA) tube, or green-top (heparin) tube. The use of gel-barrier tubes is not recommended due to slow absorption of the drug by the gel. Depending on the specimen volume and storage time, the decrease in drug level due to absorption may be clinically significant. © 2019 Laboratory Corporation of America® Holdings and Lexi-Comp Inc.

Adverse effects may include somnolence, weakness, headache and vomiting. This levetiracetam (Keppra) immunoassay uses the ARK Diagnostics reagents, which has known cross-reactivity with the drug brivaracetam (Briviact) and may report inaccurate results. Patients transitioning from levetiracetam to brivaracetam or those who are using both medications should not monitor drug concentrations with the ARK Diagnostics assay.
